GAS-BURNER.

SPECIFICATION forming part of I Jetters Patent No. 784,168, dated March7, 1905.

Application filed April 23, 1904. Serial No. 204,630.

To (all 1.0711077?! (It may cone/Hut:

Be it known that 1', RICHARD THOMAS MALIN, a citizen f the UnitedStates, residing at Denver, in the county of Denver and State ofColorado, have invented a new and useful Gas- Burner, of which thefollowing is a specification.

This invention relates to gas-burners; and it has for its object toprovide a burner for gas cooking stoves and ranges which shall be simplein construction, durable and inexpensive, and by means of which a greatamount of heat may be quickly developed and advantageously applied tothe cooking vessel placed above the burner in order that the contents ofsuch vessel may be very quickly heated and brought to a boilingtemperature, which is sometimes desirable and im portantsuch as,forinstance, in candy making, where it is frequently of great importancethat the candy should be raised to the boiling-point very swiftly inorder that the best results may be attained.

With these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of parts,which will be hereinafter fully described, and particularly pointed outin the claims.

In the accompanying drawings, Figure 1 is a top plan view of agas-burner constructed in accordance with the principles of theinvention. Fig. 2 is abottom plan view of the same. Fig. 3 1s atransverse sectional view taken on the line 3 3 in Fig. 1.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

The burner of this invention includes an annular tube or chamber 1,which is constructed preferably of cast-iron and which may be circularor polygonal in outline, as may be preferred, the upper side of saidannular tube or chamber being provided with a dished portion, forming atrough or gutter 2. The under side of this annular tube or chamber isconnected by an L 3 with a gas-supply pipe 4, which is suitablyconnected with the source of supply and which may be provided with meansfor the admission of atmospheric air into the annular chamber 1, whichconstitutes a mixingchamber. These means for the admission ofatmospheric air have been illustrated in the nature of slots 5 and afunnel (5.

7 designates a cruciform hollow casting the upper side of which isdished, as shown at 8, to form a trough or gutter. This cruciformcasting or chamber is disposed, within the annular casing l and issupported upon a gassupply pipe 9, which may also be provided with meansfor the admission of atmospheric air to the cruciform casting, whichalso constitutes a mixing-chamber.

The dished portions of the castings or casings which constitute themixingwhambers l and 7 are provided with 'jet-o .lenings 10, which areformed obliquely in the walls thereof, so that the flames emittedthereto will intersect each other, as will be readily understood. Thedished portions of said casings are likewise provided with uprights 11for the support of wire rods 12, which are plcntifully wrapped withasbestos or mineral wool, as shown at 13. The asbestos may be connectedwith the wire rods by twisting the latter spirally together and causingthe asbestos to be held between the twists or coils. Then when thelatter are placed in position and connected with the uprights 11 theasbestos iilling will be securely retained in the troughlike or dishedcavities in the upper sides of the mixing-cham bers without interferingwith the jet-openings.

It will be seen from the foregoing description that the cruciformmixing-chamber or the annular mixing-chamber may be operated eachindependently of the other; also, that when desired the two may beoperated together, thus producing a flame of great intensity and heat.Each of the gas-supply pipes will be provided with an ordinary valve, asshown at 14, for the purpose of controlling the passage of gas to themixing-chambers of the burner.

I desire it to be understood that while in the drawings hereto annexed asimple and pre ferred construction of my invention has been illustratedI do not necessarily limit myself to the structural details thereinexhibited, but reserve the right to any changes, alterations, andmodifications which come fairly within the scope of the invention andwhich may be resorted to without departing from the spirit orsacrificing the advantages of the same.

Having thus described the invention, what is claimed ising a dishedupper surface forming a trough or receptacle, uprights in said troughand 5 spirally-twisted Wires supported by said uprights, and refractorymaterial intertwisted with and secured by said wires.

In testimony that I claim the foregoing as my own 1 have hereto aflixedmy signature in 20 the presence of two witnesses.

RICHARD THOMAS MALIN.
